Definitions

  • My invention relates to vehicle entranceways and exitways and particularly to ramps associated therewith for facilitating the passage therethrough of wheelchairs and the like.
  • wheelchair ramps which can be manually slid out through a side doorway of a vehicle are known in the prior art, as for example the two U.S. Patents No. 1,717,303 and No. 1,884,513 to Barclay, the U.S. Patent No. 3,730,361 to Haynes, their operation was cumbersome and could only be effected from a position outside of the vehicle. Also none of these prior devices either utilized a portion of the ramp in its stowed position as a step, or provided for the step riser to swing upwardly so as to extend the ramp surface to the vehicle floor in the extended position of the ramp.
  • a power operated ramp to facilitate wheelchair passengers and the like in enter ⁇ ing and leaving a vehicle, such as a motor bus; to provide such a ramp which is normally stowed below the vehicle floor adjacent an entranceway to the vehicle, and, when extended, moves outwardly through the entrance ⁇ way and automatically tilts upwardly toward its inner end to provide a rigid inclined platform leading to the sidewalk or roadway exteriorly of the vehicle; to provide such a ramp whose extendable, end portion is spaced below the vehicle floor to serve as a step for other persons entering the vehicle when the ramp is in its stowed position; to provide such a ramp including a normally vertical step riser in the vehicle entranceway which swings upwardly about the adjacent edge of the vehicle floor to form the innermost end portion of the ramp when the ramp is in its fully extended position; and to provide such a ramp whose extending and retracting movements are power actuated by a lead screw extending longitudinally of the ramp and threadedly engaging a nut mounted to the step riser.
  • FIGURE 1 is a perspective view of a motor bus having a side entranceway equipped with my improved ramp, the latter being shown in its stowed position.
  • FIGURES 2 and 3 are views similar to FIGURE 1, but showing the ramp partially and fully extended, respectively.
  • FIGURE 4 is an enlarged view showing a portion of the bus in transverse vertical through the entranceway, the ramp and its associated parts being seen in the stowed position of FIGURE 1.
  • FIGURE 5 is a view similar to FIGURE 4 but showing the ramp fully extended with its outward end resting on a sidewalk, as seen in solid lines, or, as seen in broken lines, on the roadway adjacent the bus.
  • FIGURE 6 is a further enlarged fragmental view, similar to FIGURES 4 and 5, but showing the riser and other associated parts of the ramp in greater detail and at positions intermediate those of FIGURES 4 and 5.
  • FIGURES 7 and 8 are enlarged detail sectional views taken in the directions of the arrows 7-7 of FIGURE 4 and 8-8 of FIGURE 6, respectively.
  • a vehicle such as a motor bus 1, whose general configuration is best seen in FIGURES 1, 2 and 3, has an entranceway or door opening 2 through which passengers may enter or leave the vehicle when it is stopped for that purpose adjacent a curb 3 and adjoining sidewalk 4 bordering the roadway 5.
  • this door opening is located in the right hand side thereof, laterally opposite the operator's station 6 which is at the front end on the left hand side of the vehicle.
  • a ramp Extendable through the door opening 2, primarily for the convenience of wheelchair passengers, is a ramp which is designated generally by the numeral 7.
  • This ramp includes a main platform-like rigid • member 8 of generally rectangular shape which, in its stowed position (FIGURES 1 and 4) , has the major portion of its length disposed under the vehicle floor 9. When thus stowed, however, a portion of this ramp member projects laterally outward toward the door opening to form a step 10 for use of other
  • OMPI passengers in boarding and alighting from the vehicle Extending between the edge of the vehicle floor laterally opposite the door opening and this step forming portion of the platform member 8 is a riser 11 which swings to a position co-planar with the member 8 as the ramp 7 reaches its fully extended position (FIGURES 3 and 5) , such swinging movement of the riser being accompanied by upward tilting movement of the member 8 toward the vehicle floor.
  • a lead screw 12 which is recessed within an upwardly facing groove 13, best seen in FIGURES 7 and 8, provided generally centrally in the upper face of the member 8 and extending longitudinally thereof from its innermost end.
  • This groove terminates short of the outermost end of the ramp member 8 so as not to extend outwardly beyond the riser 11 when the ramp is in its stowed position.
  • a thrust bearing 13, mounted to the ramp member 8 within this groove, serves to journal the outward end of the lead screw and support it against relative longitudinal movement with the member 8.
  • the outermost end of the lead screw adjacent the bearing 13 is provided with wrench flats 14 to enable manual rotation of the lead screw in the event of a power failure.
  • the lead screw At its innermost end the lead screw is supported and rotatively driven by a reversible rotary motor 15 which is mounted to the ramp member 8. Inter ⁇ mediate of the bearing 13 and motor 15 the lead screw extends through and is threadedly engaged by a nut 16 having a connection to the vehicle floor.
  • the latter connection includes . the riser 11 whose upper extremity has a hinged connection 17 to the vehicle floor adjacent the edge thereof nearest the door opening, and a pair of brackets 18 which are attached, as by screws 19, to the back of the riser and have oppositely inturned lower leg portions 20, 21 journalably received in circular openings provided therefor in opposite sides of the nut 16.
  • a bell crank Suitably pivoted, as by the pin 22, to the vehicle is a bell crank having one arm 23 underlying the ramp member 8 and a second arm 24 which is connected to a power actuator 25.
  • This power actuator is shown for purposes of illustration as being in the form of a fluid pressure motor having a cylinder 26 pivotally connected by a pin 27 to a frame member 28 of the vehicle and having a piston rod 26' pivotally connected to the bell crank arm 24, so that when fluid pressure is applied within the cylinder 26 the rod 29 will move outwardly thereof and rotate the bell crank from its position shown in FIGURE 4 to the position shown in FIGURE 5, thereby raising the inward end of the ramp member 8 toward the level of the vehicle floor 9.
  • a microswitch 29 is preferably provided on the housing of the rotary motor 15, for actuation when the motor 15 moves into abutment with the back side of the riser 11 during outward actuation of the ramp member 8 by the lead screw 12.
  • This microswitch serves to both interrupt the power supply to the lead screw motor 15 and to initiate introduction of fluid pressure to the cylinder 26 of the bell crank actuator.
  • the riser 16 is also caused to swing upwardly and outwardly toward the door opening about its hinged connection 17 to the vehicle floor.
  • the central portion of the riser has an opening 30 therein, into which the upper ortion of the lead screw motor 15 is recessed when the riser and ramp member are in such co-planar relation.
  • Suitable anti-friction means such as rollers
  • a lamp 35 may be hinged to the riser over the opening 30 therein, to both conceal the latter and illuminate the ramp member.

Abstract

Rampe simple, mue par un moteur, commandee par un operateur, extensible (7) sur l'entree d'un autobus, sur laquelle un passager dans une chaise roulante peut se deplacer pour entrer ou sortir du vehicule a un arret sans que le conducteur du vehicule ne quitte son siege. L'autobus (11) a son extremite avant, qui, lorsqu'elle est ouverte une porte laterale permet l'extension laterale vers l'exterieur d'une rampe (7) depuis une position normale de stockage en dessous du plancher (9) du bus, une partie de la rampe adjacente a son extremite externe servant de marchepied (10) lorsque la dite rampe (7) est dans sa position arrimee (Fig. 1). S'etendant longitudinalement dans la rampe (7) et tourillonnee a son extremite exterieure se trouve une vis d'amenee (12) laquelle est mue rotativement par un moteur rotatif (15) monte a la partie interne de la rampe. Un boulon (16) engage par filetage la vis (12) et est monte de maniere a former charniere a la partie inferieure d'un releveur de marchepied (11) qui est articule a sa partie superieure au plancher du bus (9) afin d'osciller vers le haut en une position coplanaire avec la rampe (7) lorsque la rampe est entierement deployee. Un renvoi de sonnette (23, 24) ayant un bras (23) sous-tendant la rampe peut etre actionne par un moteur a fluide (25) pour faire osciller la partie interne de la rampe (7) et la partie inferieure du releveur vers leur relation coplanaire lorsque le moteur (15) vient en appui sur le boulon (16) pendant le mouvement d'extension de la rampe (7). La partie externe de la vis (12) est pourvue de meplats pour afin de faciliter la rotation de la vis (12) en cas de panne d'entrainement. Une lampe (35) cache a la fois l'ouverture (30) dans le releveur (11) et illumine la rampe (7).
